 org.archive.crawler.settings.SettingsCache
| SettingsCache | | public class SettingsCache (Code) | | This class keeps a map of host names to settings objects.
It is implemented with soft references which implies that the elements can
be garbage collected when there's no strong references to the elements.
Even if there's no strong references left elements will not be garbage
collected unless the memory is needed.
